A more fully featured version is available to paying customers of AT&T Inc , Helio, which is the wireless joint venture of Earthlink Inc and SK Telecom , and other U.S. wireless subscribers.

The new version aims to open the ability to access MySpace even wider, executives said. Versions of Fox's FoxSports.com, IGN.com and film review site Rotten Tomatoes will also launch as part of the strategy.

Amit Kapur, vice president of business development for MySpace, also said the company is exploring development of a version tailored for Apple Inc's iPhone.
